    Brivis & Rinnai

    Brivis and Rinnai ducted heating error codes

    Rinnai directs its ducted gas heater code support to the Brivis list, so the two share the same codes.

    Below is every Brivis and Rinnai ducted heating error code with a plain-English meaning. Many faults, like flame failure, overheat lockouts and pressure switch errors, are ones we see often and can usually fix on the first visit, since we are factory-trained and carry common Brivis and Rinnai parts on board. If your controller flashes a code, switch the heater off and book a licensed technician, gas faults should never be left running.
